p.16 OPERATING SYSTEMS: A Multitasking kernel (p.806 in reprint volume 11)

[author : Ken Berry]

Ken presents a task scheduler that participates in every task but is almost always invisible. The kernel lets you simulate multitasking features of the 80286 and 80386 on processors such as the 8086 and 8088. Ken's operating system, called Tele, implements a task scheduler so that it presents the same environment on various processors
